We list the “sores” of the most compact and most popular Opel crossover in Russia, which left our market along with other models of this German mark shortly after appearing.

The Opel Mokka crossover, which entered the world, including the Russian automobile market, in the fall of 2012, did not possess any special talents. However, he appeared in right time- small SUVs are at the peak of fashion. The cute appearance of the new car of the popular democratic German brand in our country was enough to win hearts Russian buyers and shoppers.

Most of them, who rarely left the asphalt and the city limits in general, did not care that Mokka small ground clearance, very conditional all-wheel drive and a cramped interior.

Despite all this, the small crossover quickly gained popularity and already in the first full year of sales in Russia it became the second most popular Opel model after the Astra. And after another year, it was already a bestseller for the brand and was among the Top 10 most popular compact rogues in our country. However, the incredible success of the model against the backdrop of a general decline in Opel sales in our country was interrupted by its sudden departure from Russia. Nevertheless, in just over three years, Russian official dealers managed to sell almost 45,000 SUVs, many of which are now available on secondary market at quite attractive prices.

Background

The first compact crossover of the Opel brand under the “coffee” name Mokka, located in model line brand one step below Antara, was first presented to the public in the spring of 2012 at the Geneva Motor Show. The model was built on the same global “Gamma II” platform as Chevrolet Aveo, as well as the last two generations of small Spark hatchbacks. The SUV went on sale in Europe in early October of the same year. In the UK, the car is known as the Vauxhall Mokka, and in North America and China, in a redesigned form, as the Buick Encore.

The model also has a “twin brother” – Chevrolet Trax. Aka Holden Trax. Initially, the SUV was produced at GM Korea facilities in South Korea. But in the fall of 2014, due to great demand for the Mocha, Opel also launched production of the crossover at a plant in Zaragoza, Spain. The SUV was updated in 2016, that is, after sales ceased in Russia. It received the name Mokka X and a sportier look. In particular, new bumpers, modified lighting equipment, revised interior and instrument panel, as well as a new 152-horsepower Gas engine 1.4.

"Secondary"

The selection of used Opel Mokka crossovers sold in our country over more than three years is not so small. In addition to three engine options and two types of gearboxes, used cars can have either front-wheel drive (50%) or all-wheel drive (50%). And both of them equally. However, four driven wheels can only be obtained on a petrol Mocha. In combination with mechanics, all-wheel drive was available on cars with a turbo engine, and with automatic transmission – only with a naturally aspirated one.

SUVs with a 6-speed automatic (54%) are found slightly more than with 5- and 6-speed manuals (46%). The vast majority of Opel Mokkas on the secondary market are equipped with a naturally aspirated 140-horsepower gasoline “four” 1.8 (75%). There are three times fewer cars with a 1.4 turbo engine of the same power (24%). And with a 130-horsepower 1.7 diesel engine under the hood, only a few are on sale (1%). After all, such crossovers were the most expensive. They were offered to customers only with an automatic transmission and only in the top-end Cosmo configuration.

Body

The very first Mokkas brought to Russia recently turned 5 years old. You shouldn’t expect any serious problems from a galvanized and well-painted crossover body, unless the car has been in an accident. Local pockets of corrosion can only appear in areas of paint chips on the hood, fenders, above the windshield and at the bottom of the doors. Don't be alarmed by the red smudges under the license plate trim on the trunk door.

The culprits of their appearance are small penny screws for fastening the decorative chrome strip with reverse side. They are easy to change. By the way, the chrome on this trim for 7,100 rubles is the first to peel off over time. Then the coating of the frame of the foglights, 1,400 rubles each, bubbles in the front bumper. Chrome flakes off less often from the false radiator grille for 4,200 rubles. The problem of bursting windshields, characteristic of Opel models originally from the 2000s, did not bypass the Mokka.

The windshield can crack both from temperature differences in the cabin and outside, and from stones falling from under the wheels of other road users. A new original one costs more than 30,000 rubles. But, having changed it more than once, SUV owners usually prefer more durable analogues from 8,000 to 12,000 rubles. Mokka's lighting equipment is also not the most durable. The plastic of the head optics, costing 10,200 rubles for a regular headlight and 39,200 rubles for xenon, peels off over time, and tail lights 15,000 rubles sometimes crack.

Engines

In Russia, the Opel Mokka was officially sold only with three fairly powerful engines, well known from the Astra J and Chevrolet Cruze. These are 140-horsepower in-line petrol fours: naturally aspirated 1.8 (A18XER) and turbocharged 1.4 (A14NET). And also a reliable 130-horsepower 1.7 diesel engine (A17DTS) developed by Isuzu engineers. The time-tested naturally aspirated 1.8 has proven itself well under the hood Opel Astra H. This engine, driven by a low-noise timing belt for 2,500 rubles, which should be changed after 120,000 km with two rollers for 4,800 rubles, is demanding on the cleanliness of the engine oil.

Failure to replace it regularly can compromise the health of the variable valve timing (CVCP) system. If it is not in order, the engine rumbles like a diesel engine. By the way, rare Russian market The Mokki diesel engine, judging by the reviews of the owners, is quite good, quite reliable and quite economical. The key to the success of its long and trouble-free operation is high-quality fuel at proven gas stations and replacement fuel filter from 1,600 rubles every 30,000 km or 2 years of operation. This engine, like other diesel engines, does not like long drives in traffic jams. It can cause failures in the EGR valve for 18,000 rubles.

“Turbo-four” 1.4 with a timing chain drive for 2000 rubles is the third most reliable in the list of Mokka engines. This modern 16-valve quality fuel and qualified maintenance, it can last at least 150,000, or even 200,000 km until major repairs. Replacements during operation of the turbo-four may require: sensor mass flow air from 7,400 rubles, a clogged adsorber valve worth 3,000 rubles or a pump for 7,900 rubles. If the turbine fails, prepare at least 37,300 rubles for a new one.

checkpoint

Not all Mokka gearboxes were received from Astra. Instead of the F17 5-speed manual transmission, the petrol “atmospheric” crossover received a D16 manual transmission with the same number of steps. But the 6-speed M32 is the same as in Opel hatches. When choosing a car with the first one, pay attention to the integrity of the seals and gaskets - this box sometimes suffers from oil leaks. She, like the second, because of his low level There are problems with bearings from 400 rubles, synchronizers for 4500-5000 rubles and with a differential.

So don’t miss extraneous hums, noises and vibrations in the box during a test drive and pay attention to the clarity of gear shifting. Despite their shortcomings, both mechanical boxes“Mocky” is still more reliable than the GM 6T40 6-band automatic transmission, also from Astra. In addition, he can be thoughtful and leisurely. In order for the automatic transmission to work better, the oil in it should be changed more often than the prescribed 50,000 km. Modernized machines on cars no older than 2014 are considered the least problematic.

They should not overheat, and the operation of the torque converter should not cause any complaints. The all-wheel drive transmission with an electronically controlled Borg Warner multi-plate clutch is reliable and does not cause any concern. Unless the previous owner drove the car into the mud and drove it through deep puddles, considering the Mokka an SUV. In this case, repair or replacement may be required as follows: the electronic unit couplings under the bottom for 14,900 rubles, and the coupling itself for 80,000 rubles.

Rest

Chassis "Mocky" without big problems and losses last at least 100,000 km. Before this mileage, replacement may require front shock absorbers for 5,700 rubles and stabilizer struts for 800 rubles. Ball joints 1300 rubles each and wheel bearings 3100 rubles each often last on a crossover for not much more than 30,000 km. Brake pads from 900 rubles do not often survive up to 50,000 km. But brake discs for 3,800 rubles last twice as long. When it comes to electrics, things are worse for the Opel Mokka.

Moreover, problems often occur with equipment on which the operation of the engine directly depends. For example, the ignition module for 12,150 rubles in gasoline versions of the SUV sometimes begins to act up after 60,000 km. Not every Mokka travels more than 100,000 km with the same generator, which costs 25,800 rubles. At the same mileage, you may have to change the radiator fans for 12,200 rubles due to the low service life of their bearings. Well, ABS sensors on the front wheels can “die” with enviable regularity every 50,000 km from moisture getting into them.

How much?

Prices for used Mokkis in Russia start at about 580,000 rubles for early copies from 2012 with a basic 1.8 naturally aspirated gasoline engine, 5-speed manual transmission, front-wheel drive and a range of up to 150,000 - 180,000 km. Crossovers with a 1.4 turbo engine can be found a little more expensive - from 600,000 rubles. And for diesel options, their current owners are asking a minimum of 790,000 rubles.

All-wheel drive Opel Mokka, both manual and automatic, are offered from about 620,000 rubles and more. The most recent crossovers sold from dealer surplus in 2015 are valued at a maximum of 1,100,000 rubles. Most often these are cars in the top-end Cosmo configuration with leather interior, rich equipment, all-wheel drive and automatic transmission. Their mileage usually does not exceed 50,000 km.

Our choice

A small, attractive, used Opel Mokka, despite having some problems and “sores,” can be a good purchase. After all, a dynamic, trendy-looking crossover with a bright appearance, decent equipment and decent interior quality for about the price of a new Solaris is an excellent offer. When choosing such a car, it is better to give preference to the version with the least problematic combination of 1.8 naturally aspirated petrol and manual transmission.

It is quite possible to find such a crossover in decent condition with a mileage of up to 100,000 km and one owner in the title for about 700,000 rubles. If you definitely need a crossover with an automatic transmission, then it is also better to look for one with this engine and preferably no older than 2014. But such a car will cost significantly more. Overpay for automatic transmission you will need at least 50,000 - 100,000 rubles. But on the other hand, you will get a car not only with an automatic transmission, but also with automatically connected all-wheel drive.

Malfunctions, engine repair Z18XER/A18XER

The A18XER engine is the same Z18XER, but strangled to comply with Euro-5 environmental standards, this is the same engine.
In South Korea, the same engine is produced under the name for Chevrolet Cruzes, Opel Mocha and other cars. The Z18XER engine replaced the Z18XE in 2005. This is a regular simple inline four with a 16 valve head. Diameter intake valves 31.2 mm, exhaust 27.5 mm. A system of variable valve timing on both shafts is used here. This is a good thing, but it often fails solenoid valves phase regulator and the motor makes sounds similar to the operation of a diesel engine. Usually the valves are cleaned, but if there is no effect, then they are replaced. In contrastfrom old GM engines, 1.8 liters. A variable-length receiver is used, which provides additional advantages. The Z18XER engine uses a good, durable timing belt with a replacement period of 150 thousand km. In addition, the EGR system is not used, which is more of a plus than a minus. The thermostat on the Z18XER is not the most reliable thing and often requires replacement before the mileage reaches 80 thousand km.

Once every 100,000 km you need to adjust the valves, because... There are no hydraulic compensators on the A18XER/Z18XER; adjustment occurs by selecting calibrated glasses. Valve clearances on a cold engine: intake - 0.21-0.29 mm, exhaust 0.27-0.35 mm.
The ignition module on the Z18XER, like the thermostat, does not last long and after 70-90 thousand km requires replacement. Is your engine running rough? Perhaps it is the ignition module; often the reason is saving on spark plugs and not replacing them in a timely manner.
In addition, leaks from the oil cooler on the Z18XER/A18XER are common, don’t be surprised or worry, repairs cost pennies.

The service life of the A18XER engine is 200-250 thousand km and is highly dependent on operation. In general, when choosing between 1.6 and 1.8 A18XER, choose the latter; with some illnesses you get a more powerful and high-torque engine.

Opel Mokka– the first model of the German automaker in the segment compact crossovers. For a long time, Opel did not dare to produce cars in this category, while competitors had already filled this niche. Today, every self-respecting automaker is trying to break into this segment, since in recent years more and more people are eager to drive exclusively crossovers, they say, they have cross-country ability, yes, and, it seems, safer. One could argue with both points, but today’s story will focus not on the functionality and practicality of this model, but on its reliability and how justified the purchase of an Opel Mokka on the secondary market will be.

A little history:

The Opel Mokka car does not yet have a long history, since it is actually being written from scratch. Opel presented the concept of its future crossover in 2011, the main task that was set for the new product was to win back part of the audience from the Nissan Zhuki like it. The production copy was first presented at the Geneva Motor Show in early 2012, and already in the middle of the same year the car went on sale. At the end of 2012, in a European automobile competition, the new product was awarded the title “Car of the Year 2012.” The Opel Mokka is the smallest crossover in class B, which is why it received the comic nickname “jeep for girls.” The name “Mokka” comes from the Arabic name for the prestigious Arabica coffee beans, from which a variety of mocha coffee drinks are prepared. It was not for nothing that marketers chose this name for the subcompact crossover: it contains a powerful associative urge - “start your day with Mokka.”

The car is built on a common platform for many passenger cars GM recent years release - Gamma II. Oddly enough, in model range Opel, Mokka ranks lower than. In some countries the car is sold under a different name: in the UK - Vauxhall Mokka, in China and the USA - Buick Encore. The production of the car was established in Germany, South Korea, Spain, Russia and Belarus. In 2013, after minor modernization, the line of power units was replenished with a 140-horsepower 1.8-liter engine. In 2014 it was introduced diesel engine 1.6 (136 hp), the power of which was reduced to 110 hp in 2015. Due to the introduction of sanctions, in 2015, sales of the car in Russia were stopped. In March 2016, a restyled version was presented at the Geneva auto show, which is now called Opel Mocha X. In the fall of the same year, mass production of the model began.

Weaknesses of Opel Mokka with mileage

Like most modern cars, the paintwork on the body is thin and not particularly durable - it quickly becomes covered with scratches and chips. Chrome elements (linings on the door handles, radiator grille and corporate logo) are also not famous for their reliability; after 3-5 years of operation, as a rule, they require replacement. As for the corrosion resistance of the body, it is still too early to talk about this, given the small age of the car. However, based on the fact that the metal in places where it is chipped does not rust for long enough, if the chip is not repaired, the metal begins to bloom after about a year, then there should not be any serious problems with the body in the future.

But the suspension elements and engine compartment mounts become rusty very quickly. Therefore, if you plan to use the car for a long time, it is advisable to treat the bottom with anticorrosive. Windshield very weak and prone to cracking, purchasing original glass is expensive, which is why a Chinese equivalent is often installed. Therefore, it will be useful and may become a reason for bargaining. The mechanism of door handles is not known for its reliability; in addition, they are very flimsy and, if excessive force is applied to them, the handle may break off.

Power units

The range of power units consists of gasoline and diesel engines, the latter were not officially supplied to most CIS countries: petrol ECOTEC - turbocharged 1.4 (140 hp) and naturally aspirated A18XER 1.8 (140 hp), there is also 1.6 (115 hp), but not officially available to us supplied; diesel CDTI - 1.6 (135 hp, from 2015 - 110 hp) and 1.7 (130 hp). From the line of power units, you can understand that the car is aimed at a calm driving style, so you shouldn’t expect “peppy” dynamics from these engines. All engines are well known and quite reliable, but if you choose between two gasoline engines, then I would give preference to an atmospheric power unit. This engine is in no way inferior in power to a turbocharged one, but with further operation it will be cheaper to maintain ( at a minimum, you can save almost 400 USD on replacing the turbine.), plus, it has a longer lifespan and warms up faster in the cold season.

Before buying an Opel Mokka, you need to pay attention to several points. The first is the work of phase shifters (tapping). A long time for the “phasics” to reach operating mode may be evidence of a malfunction of the regulator couplings, but, most likely, the control valves are in poor condition (their meshes are heavily contaminated), resulting in the creation of insufficient pressure. Second, check the condition of the antifreeze. The fact is that the cylinder block gasket loses its seal over time and oil begins to enter the cooling system, quickly contaminating it, and also rendering the rubber elements unusable, thereby increasing the likelihood of engine overheating. Over time, the crankcase ventilation valve fails, which significantly increases oil consumption due to waste and accelerates the process of contamination of the intake manifold. Once every 50-70 thousand km it is recommended to adjust the valves; this procedure is inexpensive, but significantly reduces the noise of the engine.

If you use low-quality fuel, an unpleasant surprise will await you in the intake manifold. Due to severe contamination, the dampers first begin to jam; if measures are not taken, the drive breaks. To avoid problems, it is recommended to inspect the unit once every 100,000 km. The generator resource does not exceed 150,000 km. Among the common disadvantages of naturally aspirated engines, one can note the short service life of ignition coils (average service life of 60,000 km), sensors, leaking oil seals and cylinder head cover gaskets, low quality elements of the cooling system (leaking thermostat, pump, etc.) and quite high, by modern standards, fuel consumption - 11-12 liters per hundred. It is recommended to fill the engine only with branded oil, since savings, at best, will result in the failure of the phase shifters; at worst, the oil scraper rings will become stuck, which will increase oil consumption. Timing belt drive, replacement interval 60-80 thousand km.

Unlike an aspirated engine, the turbo engine uses a timing chain drive, but this does not significantly increase the service life of the mechanism (chain service life is 120-150 thousand km). Due to the fact that the engine has a high output per liter of volume, it is heavily loaded and is demanding on the quality of fuels and lubricants - you need to pour only the oil recommended by the manufacturer, otherwise problems will not be long in coming (premature turbine failure, destruction piston group etc.). Common disadvantages include: leaking valve cover gaskets (can appear even on cars with low mileage), increased operating noise (reminiscent of a diesel engine, classic Opel engines with phase regulators).

After 100,000 km, it is recommended to replace the inflation control valve. This operation will allow you to avoid complications with inflation and over-inflating in the future. The turbine runs up to 200,000 thousand km, but has a tendency to crack in the most heat-loaded part. When using fuel of poor quality, engine detonation increases significantly, because of this, destruction of the piston partitions is possible, as a result, compression in the cylinders decreases. Very often, even with short runs, the pump begins to “howl” (whistle). Only replacing the pump will help eliminate the defect; fortunately, this part is relatively inexpensive. More extraneous sounds(clicking sound) fuel injectors may make, but, as a rule, this does not affect their performance in any way. Problem with increased vibrations Idling known to many lovers of Opel cars, there is nothing fatal in this either, it is a disease of all turbo engines of this company. The cooling system may begin to leak over time. expansion tank and a pump.

Little is known about the shortcomings of diesel engines, the only thing that can be stated with confidence is this moment, is that, like all engines equipped with a Common Rail system, they are very sensitive to the quality of diesel fuel. When using fuel from a “canister”, you should not count on a long service life of the injection pump injectors, EGR valve and particulate filter. And given the fact that 1.6 engines are tailored to Euro 6 standards, problems can start quite early. The 1.7 Isuzov engine looks preferable here, this power unit has proven itself well on cars of other brands.

Transmission

The Opel Mokka was equipped with five- and six-speed manual transmissions (F16 and M32), as well as a six-speed automatic transmission Korean made (6T40). Regardless of transmission type special attention Requires an outboard bearing. The fact is that it is located close to the exhaust system; under heavy loads, lubricant begins to leak out of it. It is not uncommon for a bearing to start humming after 60-80 thousand km. The mechanics are reliable and have a good service life, but there are still a couple of weak points here. The secondary shaft bearings and differential may be a concern, but they, as a rule, fail after 200,000 km. On many cars, after 100-150 thousand km, the accuracy of the operation of the rocker decreases, and oil leaks appear at the joints.

But the automatic transmission cannot boast high level reliability, especially when paired with a turbocharged engine. Serious problems with mechanical part transmissions begin after 150-180 thousand km - the solenoids and their block, valve body, torque converter, bushings, friction discs, and gas turbine engine blocking lining fail. A little earlier, jerking may appear when switching from 3-4-5-6, most often the cause is wear of the wavy spring. If the problem is not corrected in a timely manner, the drum will need to be repaired or the planetary gear replaced in the future. Also, jerks and delays when shifting gears may indicate not only technical problems boxes, but also about software failures. In 2014, the transmission was modernized, which increased its reliability. To extend the life of the automatic transmission, you should avoid overheating the transmission, monitor the oil level and try to change it along with the filter every 50,000 km.

Despite the presence of all-wheel drive, it is still not worth considering the Opel Mokka for hunting and fishing trips. Firstly, ground clearance too small for such trips. Secondly, this transmission overheats quite quickly during intense slipping, because of this its service life is significantly reduced. Four-wheel drive implemented using a BorgWarner coupling, if you do not “force” it, there should be no problems with it. To improve the performance characteristics of the unit, it is advisable to clean it and change the lubricant every 3-4 years. At the same interval, it is recommended to readjust the gaps in the clutch pack. Weak point is the clutch control unit. The fact is that it is located not far from the coupling and suffers greatly from exposure to reagents, dirt and moisture. To extend its service life, periodic cleaning of the connectors is required; in advanced cases, it is necessary to change the wiring.

Reliability of used Opel Mokka chassis

The suspension is structurally simple, but due to the fact that a beam is installed at the rear, the Opel Mokka turns out to be a little harsh on the move (MacPherson struts are traditionally used at the front). What surprised me most was that the beam is also installed on all-wheel drive versions, but with a slightly different shape (competitors on all-wheel drive versions have a “multi-link”). If we talk about the reliability of the chassis, then it is worth noting the short service life of the ball joints - they can become unusable after 30,000 km. There are also problems with reliability wheel bearings– fail after 60-70 thousand km. On top trim levels with 18-inch wheels the problem may appear at an earlier mileage. Stabilizer struts and bushings last up to 50-80 thousand km. The remaining original suspension elements have been maintained for more than 100,000 km. Also, it is worth noting the expensive cost of replacing some original parts and the small resource ABS sensors– 50-70 thousand km.

The steering system was equipped with two types of amplifiers - a hydraulic booster was installed on the naturally aspirated engine, and an electric one on the others. The power steering is quite reliable, but is afraid of severe frosts - it has an unfortunate location, which is why the fluid in it practically does not warm up. This feature causes premature failure of the pump and rack leakage. The disadvantage of electric power steering is the malfunction of the steering wheel position sensor. Also, there are complaints about the reliability of the connectors on the power module itself - they burn out over time. Brake system reliable, the only thing that is a little frustrating is the creaking brake pads, unreliability parking brake And high price consumables. The service life of the pads is 40-60 thousand km; discs are 100-120 thousand km.

Salon

The interior of the Opel Mokka, from a distance, is somewhat reminiscent of a Porsche Cayenne, but as soon as you get inside, you immediately feel the difference - inexpensive finishing materials, but in places the build quality is poor. The main disadvantages include poor sound insulation, the appearance of crickets and scratches on the plastic, signs of wear appear on the steering wheel early (70-100 thousand km), the gearshift lever and steering column become loose over time. Under drivers weighing more than 90 kg, after 3-5 years of operation the seat cushions sag. Also, the disadvantages include the appearance of condensation on the ceiling. As for electrical equipment, the heater motor is a problem here - backlash appears on a car with a mileage of more than 100,000 km. From time to time, the light sensor of the AFL system (installed in the rear view mirror) bothers us. The performance of the sensor may be affected by a video recorder installed nearby. In addition, the air conditioner compressor bearing likes to make shuffling sounds, which greatly frightens the owners. Some owners reflash the instrument panel, this manipulation allows you to display readings about the temperature of the automatic transmission fluid and the battery charge level ( Buick firmware).

Result:

Despite the large number of all kinds of problems, the Opel Mokka cannot be called a problem car, since most of the troubles arise as a result of poor or untimely maintenance. Today on the secondary market you can get a very good option for adequate price However, we should not forget that Opel quickly loses value and Mokka is no exception. The cost of service is no more than that of competitors, and in some cases even cheaper.

If you are the owner of this car model, please describe the problems that you encountered while using the car. Perhaps your review will help the readers of our site when choosing a car.

FUNCTIONAL PURPOSE OF THE TIMING BELT

Replacing the timing belt is part of the routine Maintenance Opel car Mokka and plays an important role in engine performance vehicle. Untimely replacement of the belt can lead to malfunction of the engine, and a break can lead to deformation of the timing valve and the need for repairs. overhaul engine.

All parts of the gas distribution mechanism are closely connected to each other; the injection of the air-fuel mixture drives the piston of the engine cylinder, which in turn pushes the crankshaft, connected by a drive belt to camshaft. Thus, the camshaft moves, which regulates the frequency of valve movement. The Opel Mokka timing belt connects the gears together and transmits torque from the crankshaft to the camshaft, affecting its rotation speed. If the system is working properly, their speed should be equal.

TYPES OF TIMING BELT FAULTS

1. Wear of the timing belt leads to a change in the torque transmission force from the crankshaft to the camshaft, resulting in a change in the frequency of movement of the engine pistons and valves. This, in turn, leads to a malfunction of the gas distribution system, rapid heating of the engine and, as a consequence, a decrease in engine power and an increase in consumption of the fuel mixture. For reliable and uninterrupted operation of the engine, it is necessary that the valves close and open at the same frequency as the engine pistons. If the timing belt slips due to wear, it can cause a breakage.
2. A broken Opel Mokka timing belt is the most dangerous damage to the engine. If such a malfunction occurs, the camshaft ceases to be connected to the crankshaft and can stop completely arbitrarily in a position in which any of the valves of the gas distribution mechanism is open. In this case, the piston, moving upward, may collide with the valve, which will lead to its deformation. In this case, the car engine faces serious repairs. It should be noted that a timing belt break does not occur unexpectedly; it is almost always accompanied by changes in the operation of the car engine, a decrease in its power, a change in gasoline consumption, the appearance of extraneous squeaks, creaks, etc.

To prevent and prevent the operation of the gas distribution mechanism, it is necessary to periodically replace the timing belt; this will save the Opel Mokka engine from breakdown, prevent premature engine wear and increase its service life.
